Description

【０００１】
【発明の属する技術分野】
本発明は、伸縮装置と、それを利用したボクシングするロボット玩具に関するものである。
【０００２】
【従来の技術】
従来、２つの部材からなる伸縮装置は、例えば、第１の部材と、第１の部材に摺動自在に設けられた第２の部材とからなり、第２の部材にラックを形成し、第１の部材にラックに噛み合う駆動歯車を設け、この駆動歯車を正転・逆転させることにより、第２の部材を摺動させて、伸縮を行っていた。また、３つ以上の部材からなる伸縮装置にあっては、各部材間にアクチュエータを設け、各アクチュエータを作動させて、伸縮を行っていた。
【０００３】
また、従来のボクシングするロボット玩具は、上記した従来の伸縮装置を腕部材に利用して、ボクシング動作をさせていた。
【０００４】
【発明が解決しようとする課題】
従来の伸縮装置は、駆動歯車を駆動する駆動モータと電源、アクチュエータを作動させる電源、油圧等を必要とするため、構造が複雑となり、高価になるという問題点があった。また、従来のボクシングするロボット玩具は、上記伸縮装置を利用した腕部材を作動させるための駆動モータ、電源等を胴部内に組み込む必要があるため、構造が複雑で重量があり、安価に製造することができないという問題点があった。
【０００５】
本願発明は、上記問題点に鑑み案出したものであって、構造が簡単で安価に製造することができる伸縮装置を用いて、左右両方の腕を伸縮させることができる、従来にない新規な構造のロボット玩具を提供することを目的とする。

ロボット玩具１は、上記構成を有し、図１の初期状態では、左腕部８０と右腕部９０が縮んだ状態になっている。すなわち、左右上腕部８１，９１内に左右下腕部８２，９２が収納され、左右下腕部８２，９２内に左右手部８３，９３が収納されている。この時、図４（ａ）に示すように、駆動プーリ６１によって、第１の牽引紐７６が伸ばされて緩められ、第２の牽引紐７７が巻き付けられて左右手部８３，９３が引っ張られた状態である。駆動プーリ６１は、これの爪クラッチ６２が伝達車６０の爪クラッチ５９に圧接し、伝達車６０が弾性片７９に押圧されているので、回転しないようになっている。また、中間軸５０，５０の小歯車５１，５１は、部分クラウン歯車２０の半円状の歯２１と噛み合っていない。
【００５０】
ロボット玩具１は、下半身部２を固定して、胴部７１を矢印に示すように、右旋回させると、図３に示すように、ブロック部材３５も右側に回転し、ブロック部材３５の左側に設けられた小歯車５１が部分クラウン歯車２０の歯２１と噛み合う。そのため、小歯車５１は回転し、この回転が平歯車５２、ピニオン５６、回転軸５５、伝達車６０、爪クラッチ５９、爪クラッチ６２を介して左側の駆動プーリ６１に伝達され、左側の駆動プーリ６１が回転する。なお、ブロック部材３５の右側に設けられた小歯車５１は、部分クラウン歯車２０の歯２１と噛み合わないため、右側の駆動プーリ６１は回転しない。また、胴部７１は、これの係合部７５がねじりバネ１７の一端１７ａに係合しているので、左旋回方向に付勢されている。
【００５１】
左側の駆動プーリ６１が回転すると、図４（ｂ）に示すように、第２の牽引紐７７が緩められ、同時に第１の牽引紐７６が巻き付けられて引っ張られ、第１の支軸８４と第２の支軸８５間が短くなって左下腕部８２が左上腕部８１内から引き出され、さらに第３の支軸８６と第４の支軸８７間が短くなって左手部８３が左下腕部８２内から引き出され、左腕部８０が伸びた状態になる。この伸びた状態も、駆動プーリ６１は、これの爪クラッチ６２が伝達車６０の爪クラッチ５９に圧接し、伝達車６０が弾性片７９に押圧されているので、維持される。
【００５２】
左腕部８０が伸びた状態から、胴部７１を離すと、ねじりバネ１７の弾性復元力により、胴部７１が矢印の反対方向に左旋回し、ブロック部材３５も左側に回転し、小歯車５１が逆回転し、この逆回転が平歯車５２、ピニオン５６、回転軸５５、伝達車６０、爪クラッチ５９、爪クラッチ６２を介して左側の駆動プーリ６１に伝達され、左側の駆動プーリ６１が逆回転する。なお、ブロック部材３５の右側に設けられた小歯車５１は、部分クラウン歯車２０の歯２１と噛み合わないため、右側の駆動プーリ６１は回転しない。
【００５３】
左側の駆動プーリ６１が逆回転すると、図４（ｂ）に示すように、第１の牽引紐７６が緩められ、同時に第２の牽引紐７７が巻き付けられて引っ張られ、左手部８３が左下腕部８２内に収納され、左下腕部８２が左上腕部８１内に収納され、左腕部８０が元の縮んだ状態に復帰する。このように、胴部７１を右旋回、即ち左肩部を前側に出すと左腕部８０が伸び、胴部７１を元の状態に戻すと左腕部８０が元の縮んだ状態に戻ることになる。同様に、胴部７１を左旋回、即ち右肩部を前側に出すと右腕部９０が伸び、胴部７１を元の状態に戻すと右腕部９０が元の縮んだ状態に戻ることになる。
【００５４】
【発明の効果】
以上説明してきたように、本願発明に係るロボット玩具は、複雑な歯車機構を必要とせず、牽引紐で伸縮させることができる、構造が簡単且つ軽量、コンパクトで、安価に製造することができる伸縮装置を腕部として利用するので、胴部内に駆動モータ、電池等を収容する必要がなく、構造が簡単で、軽量化を図ることができ、安価に製造することができるという効果がある。

[0049]
The robot toy 1 has the above configuration, and in the initial state of FIG. 1, the left arm portion 80 and the right arm portion 90 are in a contracted state. That is, the left and right lower arms 82 and 92 are accommodated in the left and right upper arms 81 and 91, and the left and right hand portions 83 and 93 are accommodated in the left and right lower arms 82 and 92. At this time, as shown in FIG. 4A, the first pulling cord 76 is stretched and loosened by the drive pulley 61, the second pulling cord 77 is wound and the left and right hand portions 83 and 93 are pulled. State. The drive pulley 61 is prevented from rotating because the pawl clutch 62 is pressed against the pawl clutch 59 of the transmission wheel 60 and the transmission wheel 60 is pressed against the elastic piece 79. Further, the small gears 51, 51 of the intermediate shafts 50, 50 do not mesh with the semicircular teeth 21 of the partial crown gear 20.
[0050]
When the robot toy 1 fixes the lower body part 2 and rotates the torso part 71 to the right as shown by the arrow, the block member 35 also rotates to the right as shown in FIG. The small gear 51 provided on the meshing gear meshes with the teeth 21 of the partial crown gear 20. Therefore, the small gear 51 rotates, and this rotation is transmitted to the left driving pulley 61 via the spur gear 52, the pinion 56, the rotating shaft 55, the transmission wheel 60, the pawl clutch 59, and the pawl clutch 62, and the left driving pulley. 61 rotates. Since the small gear 51 provided on the right side of the block member 35 does not mesh with the teeth 21 of the partial crown gear 20, the right driving pulley 61 does not rotate. Further, since the engaging portion 75 of the trunk portion 71 is engaged with the one end 17a of the torsion spring 17, the trunk portion 71 is biased in the left turning direction.
[0051]
When the left driving pulley 61 rotates, as shown in FIG. 4B, the second traction string 77 is loosened, and at the same time, the first traction string 76 is wound and pulled, The distance between the second support shafts 85 is shortened, and the left lower arm portion 82 is pulled out from the left upper arm portion 81. Further, the distance between the third support shaft 86 and the fourth support shaft 87 is shortened, and the left hand portion 83 is left lower arm. The arm 82 is pulled out from the inside of the part 82, and the left arm part 80 is extended. The extended state of the drive pulley 61 is also maintained because the pawl clutch 62 is pressed against the pawl clutch 59 of the transmission wheel 60 and the transmission wheel 60 is pressed against the elastic piece 79.
[0052]
When the body 71 is released from the state in which the left arm 80 is extended, the body 71 turns left in the direction opposite to the arrow due to the elastic restoring force of the torsion spring 17, the block member 35 also rotates to the left, and the small gear 51 moves. The reverse rotation is transmitted to the left driving pulley 61 via the spur gear 52, pinion 56, rotating shaft 55, transmission wheel 60, claw clutch 59, and claw clutch 62, and the left driving pulley 61 rotates in the reverse direction. To do. Since the small gear 51 provided on the right side of the block member 35 does not mesh with the teeth 21 of the partial crown gear 20, the right driving pulley 61 does not rotate.
[0053]
When the left driving pulley 61 rotates in the reverse direction, as shown in FIG. 4 (b), the first traction cord 76 is loosened, and at the same time, the second traction cord 77 is wound and pulled, and the left hand portion 83 is moved to the left lower arm. The left lower arm portion 82 is accommodated in the left upper arm portion 81, and the left arm portion 80 returns to the original contracted state. As described above, when the trunk 71 is turned right, that is, when the left shoulder is moved forward, the left arm 80 is extended, and when the trunk 71 is returned to the original state, the left arm 80 returns to the original contracted state. . Similarly, when the trunk 71 is turned left, that is, when the right shoulder is moved forward, the right arm 90 is extended, and when the trunk 71 is returned to the original state, the right arm 90 returns to the original contracted state.
